7 Claims.

The invention relates to improvements in goggles used for protectionagainst dust and the like, and against glare, and it aims primarily toprovide a novel construction in which the lenses may be swung to openpositions to facilitate cleaning of their inner sides without thenecessity of removing the head gear from the head.

Another object is to provide novel means for holding the lenses innormal closed position until forced from said position.

Yet another object is to provide novel means whereby the lenses may beheld in vertical rearwardly swung position until forced therefrom, iftheir use be temporarily unnecessary.

Yet another object is to provide a novel construction for hingedlymounting the lenses upon the customary eye-encircling walls ofthegoggles.

A still further aim is to provide the lenses with downwardly projectingfinger-pieces by means of which they may be readily opened or closed,and to provide U-shaped spring clips which cooperate with saidfinger-pieces to hold the lenses in closed position.

Yet another aim is the provision of novel spring fingers on certainleaves of the lens hinges and cooperable with the other leaves of saidhinges to yieldably hold the lenses in open position.

With the foregoing and minor objects in view, the invention resides inthe novel subject matter hereinafter described and claimed, descriptionbeing accomplished by reference to the accompanying drawings.

Figure l is a perspective view showing one form of construction, thelenses being in closed position.

Figure 2 is a view similar to Fig. 1 but showing the lenses in openposition.

Figure 3 is a horizontal sectional view through substantially one-halfof the goggles as indicated by line 3-3 of Fig. 1.

Figure 4 is a detail vertical sectional view on line 4-4 of Fig. 3.

Figure 5 is a detail vertical sectional view on line 5-5 of Fig. 1.

Figure 6 is a fragmentary perspective view showing a somewhat differentform of construction.

Figure 7 is a detail horizontal sectional view on line 1-1 of Fig. 6.

Figure 8 is a detail vertical section on line 8-8 of F18. "I.

Figure 9 is a detail vertical section on line 99 of Fit. 6.

In the drawings above briefly described, l0 denotes two more or lessconventional eye-encircling walls formed from plastic or any otherdesired material and connected by a nose bridge ll forming no part ofthe present invention. Straps l2 are shown connected with the rear endsof the walls In to hold them in proper posi- 1 tion against the face butthe present invention is not concerned with how the goggles are mountedupon the head, nor with how the eye-encircling walls are connected witheach other. The features of novelty are associated wiih the lenses Hwhich are normally disposed at the front ends of the walls Hi, thelatter being preferably provided with internal forwardly facingshoulders Ill which are engaged by said lenses each lens I3 is providedwith a downwardly projecting finger-piece l9 which is soldered orotherwise secured to the band or rim l4, whereas in- Figs. 6 to 9, thecorresponding finger-piece I9 is fastened to the lens by suitablefasteners 20.

In both forms of construction, the outer side portion of eacheye-encircling wall III is formed with a lateral ventilating opening 2|.In Figs. 1 to 5, a woven screen 22 covers each opening 2| and isprovided with a marginal frame 23 to which the other leaf 24 of thehinge I1 is soldered or otherwise secured. In Figs. 6 to 9, however, aperforated sheet metal screen 22 extends over each opening 2| and isprovided with an integral marginal frame 23, which frame is integralwith the hinge leaf 2 corresponding to the leaf 24. The construction ofeach marginal frame 23, 23', is preferably such that it is provided withone flange 25 lying against the exterior of the wall ill, with anotherflange 26 fitting into the opening 2|, and with a plurality of lugs 21carried by the flange 26 and clinched against the inner side of the walll0. It will thus be seen that each marginal frame is securely fastenedto the wall In and that said frame not only or it, the lens being thusheld in this position until forced therefrom.

The lower side'of each eye-encircling wall II .is provided with aU-shaped spring clip III to yieldably embrace the finger-piece I! or IIand thus hold the lens II in closed position until forced from thisposition, the clip being secured to the wall III by a suitable fastenerII. The lower front portion of each wall It is, of course, provided witha suitable notch 32 to receive the finger-piece I 9 or II' when the lensis closed,

and the outer front portion of each wall is notched at 81 to accommodatethe hinge leaf I O and the lens rim connection I, or the hinge leaf II.

From the foregoing, taken in connection with the accompanying drawings,it will be seen that novel and advantageous provision has been made forcarrying out the objects of the invention. By means of thefinger-pieces, the lenses may be easily opened or closed withoutdisturbing the positions of the eye-encircling walls II or any otherportions of the goggles. With the lenses closed, their outer sides maybe readily cleaned, and when said lenses are swung to open position,their inner sides are exposed for cleaning. The lenses will be yieldablyheld in either open or closed position until pushed therefrom; saidlenses may be closed and used whenever desired: and when their use isunnecessary, they may be moved to open position, leaving the head gearon the head, however, so that the lenses may be repositioned for usewhenever required.

As excellent results are attainable from the details disclosed, suchdetails are preferably followed. However, within the scope of theinvention as claimed, variations may be made.

I claim:

1. In a pair of goggles, an eye-encircling wall, a lens normallyoccupyin a closed position at the front end of said wall, avertical-axis hinge connecting said lens with said wall and permittingoutward and rearward swinging of said lens to an open position in whichit extends longitudinally at the outer side of said wall, a finger-piecepro- Jecting downwardly from said lens for swinging it to and from openand closed positions, a spring detent for holding said lens in closedposition until forced therefrom, and an additional spring I 2. In a pairof go gles, an eye-encircling wall, a lens at the front end of saidwall, a hinge having two leaves at substantially right angles to eachother, one of said leaves being secured to the outer side of said wall.the other of said leaves being secured to said lens, a spring fingerprojecting outwardly from one edge of said one of said leaves toyieldably engage the corresponding edge of said other of said leaveswhen said lens is swung to an open position at the outer side of saidwall, and releasable means for normally holdinssaid lens in closedposition.

3, In a pair of goggles, an eye-encircling wall having a lateralventilating opening, a lens at the front end of said Well, a screenhaving a rigid marginal frame secured to said wall around said opening.a hinge having one leaf rigidly secured to said marginal frame and asecond leaf rigidly secured to said lens, whereby said mar- 81110.1frame serves to attach both said screen and said hinge to said wall, andreleasable means {or normally holding said lens in closed posi- 4. Astructure as specified in claim 3, said one leaf and said marginal framebeing integrally Joined to each other.
